How-To

On this page, you’ll find quick, easy answers that are up to date for the latest firmware – slanted more towards “power users” or old school Commodore 64 aficionados that may be coming from real hardware or emulation packages.

Configuration Files / CJM / Filename Parameters

With emulators, I can set certain things like joystick and turbo loading speeds, etc. Can I do that somehow with TheC64Mini?

Designed to be simple, TheC64Mini does not have many “emulation” features available in the user interface. However, it is very robust with methods of controlling several emulation features. This is done using a simple filename rename of the game or using a “companion” text file named the same as the disk with the .cjm extension.

What emulation options can be changed?

Default Joystick port to use (port 2 is the default)

Whether “accurate drive emulation” is on or off

PAL or NTSC settings

Read Only option so the disk cannot be written to

Hiding the drive loading icon when in “accurate drive emulation” mode

Vertical display shifting of pixels (if a game intrudes on C64 borders)
